What’s New

The following are some of the new features and enhancements in Themer 1.1. To learn more, please watch our recent webinar, Build Great Looking Themes with Themer 1.1.

Extensive Support for Creating UI Mixins

Ext JS components have UI mixins for generating multiple visual renditions of the component. Themer 1.1 makes it easy to create and style UIs for a large number of components including modern grid, list, tabpanel, title bar, and form components. As you start creating UIs within Themer, you will get access to all Sass variables to customize and create a distinct look for your application components. For modern grid UIs, you can uniquely theme grid cells, grid column header, row, group header row, and paging toolbar.

Easily Navigate and Style Components with Component Tree

Themer 1.1 adds support for component tree, which provides a powerful way to navigate, select, and style components in your app. The component tree is visible within Themer when you start inspecting your application. When you click any part of your application in the browser, the corresponding component in the component tree is selected. Then, you can configure Sass variables for that component.

Import Colors from Existing CSS File

Themer 1.1 allows you to import colors from your existing CSS file and add those to the color palette. In the color palette, click on the “upload” icon, select your CSS file, and you’ll have the option to select colors that you can add to the color palette. The added colors are shown in the color palette along with colors that are lighter and darker in increments of +/- 5%.

Quickly Connect Your App to Themer with Bookmarklet

Themer enables you to directly inspect styles of your connected application and modify it. To connect your app to Themer, you will need to change app.json as specified in the Themer docs. With Themer 1.1, you have the additional option to connect with the bookmarklet, which can be found in Themer under View > Connected Apps. The bookmarklet will be generated using the port that Themer is using. You can drag the bookmarklet from Themer to your browser bookmarks bar. Once you have your app running in a browser, click on the bookmarklet to connect the app to Themer.
